When the depth d = 0, the value of g on the surface of the earth g d = g. When the depth d = R, the value of g at the centre of the earth g d = 0. The force exerted by the earth on an object is called the gravitational force (F). In fact, its mean radius of 3.389 km is the equivalent of roughly 0.53 Earths, while its mass (6.41711023 kg) is just 0.107 Earths. Mass of the Earth is 6 10 24 kg. If one were to stand on it, they would simply sink until they eventually arrived at its (theorized) solid core. F The general rule is that acceleration decreases with height: higher objects have less acceleration. The acceleration due to gravity on the surface of the moon is 1.620 m/s 2. Depending on the size, mass and density of the object, the gravitational force it exerts varies.
